What is a storage unit?
A storage unit, also known as a storage device, is a hardware component used to save digital data permanently or temporarily in a computer system. It allows the system to store operating systems, software applications, files, and other types of data so that they can be accessed and used when needed. Storage units come in various forms, including hard disk drives (HDDs), which use magnetic storage to save large amounts of data at a relatively low cost, and solid-state drives (SSDs), which use flash memory to provide faster data access speeds and greater durability. Other types of storage units include optical drives, such as CD or DVD drives, and external storage devices like USB flash drives and external hard drives. The capacity, speed, and type of storage unit play a significant role in the overall performance and usability of a computer.
